Specific embodiments of the present invention are described below with reference to the drawings.

For ease of explanation, the following definitions are used to refer to "front," "rear," "left," "right," "upper," and "lower," as shown in Figures 1 to 8. The "front-rear direction," "left-right direction," and "upper direction" are mutually perpendicular. The "front-rear direction," "left-right direction," and "upper direction" are directions seen by a user sitting in the driver's seat or passenger seat of the vehicle. The "front-rear direction" corresponds to the "axial direction" in this invention.

First Embodiment
The holding device 1 shown in Figures 1 and 2 is a device that is installed on an instrument panel of a vehicle or the like and holds a smartphone 2. As shown in Figure 1, the holding device 1 includes a holding unit 3 that holds the smartphone 2, a rotating unit 4 that rotates the holding unit 3 around an axis along the front-rear direction, a holding unit 5 that holds the rotating unit 4, and an in-vehicle ECU (Electronic Control Unit) 6 (see Figure 2) as a rotation control unit that controls the rotation of the rotating unit 4 based on vehicle information indicating the state of the vehicle.

The smartphone 2 has a display screen 21 on the front side, and a ferromagnetic material such as iron that is attracted to a magnet and a magnet are built into the back side.

As shown in FIG. 1, the holding portion 3 has a permanent magnet 8 and an electromagnet 9 as a first electromagnet.

The permanent magnet 8 is arranged in a disk shape that is arranged perpendicular to the front-to-rear direction, and is arranged to attract the ferromagnetic material or magnet built into the smartphone 2. In this embodiment, the permanent magnet 8 has its south pole and north pole aligned along the front-to-rear direction. In other words, the permanent magnet 8 is arranged so that its magnetization direction is along the front-to-rear direction.

The electromagnet 9 is arranged in a ring shape, with the permanent magnet 8 fitted and fixed in the center. In this embodiment, the electromagnet 9 has a coil (not shown) wound around an axis along the front-rear direction, and like the permanent magnet 8, the north pole and south pole are arranged side by side along the front-rear direction. In other words, the electromagnet 9 is arranged so that the magnetization direction is along the front-rear direction. When a current is passed through the coil of the electromagnet 9 so that the coil has the same magnetization direction as the permanent magnet 8, a magnetic force is generated that attracts the smartphone 2 to the electromagnet 9. When a current is passed through the coil of the electromagnet 9 so that the coil has the opposite magnetization direction to the permanent magnet 8, a magnetic force is generated that repels the smartphone 2 from the electromagnet 9.

The rotating unit 4 includes a rotating shaft that rotates around an axis along the front-rear direction, and a motor (neither shown) that rotates the rotating shaft. The rear end of the rotating shaft is fixed to a permanent magnet 8, and when the rotating shaft is rotated by the motor, the permanent magnet 8 and the electromagnet 9 fixed to the permanent magnet 8 also rotate around an axis along the front-rear direction. When the permanent magnet 8 rotates, the smartphone 2 also rotates.

The holding part 5 is fixed to the vehicle, for example to the instrument panel, and holds the rotating part 4.

As shown in FIG. 2, the on-board ECU 6 is connected to the coil of the electromagnet 9 and the motor of the rotating part 4, and controls the magnetic force of the electromagnet 9 and the rotation of the rotating part 4. The on-board ECU 6 is connected to a data communication unit 10 that enables communication with an in-vehicle network such as an in-vehicle LAN. The on-board ECU 6 receives vehicle information (e.g., shift information indicating the position of the shift lever, on/off information of the ignition switch, vehicle speed information, etc.) from the in-vehicle network via the data communication unit 10.

The in-vehicle ECU 6 is connected to a data communication unit 11 that enables communication with the smartphone 2. The in-vehicle ECU 6 receives electronic device information (model and type number information of the smartphone 2) and orientation information (whether the smartphone 2 is placed vertically or horizontally) from the smartphone 2 via the data communication unit 11.

Next, the procedure for using the holding device 1 configured as described above will be described. The user brings the back of the smartphone 2 close to the permanent magnet 8 or electromagnet 9. As a result, the smartphone 2 is attracted to the permanent magnet 8 or electromagnet 9 by the magnetic force of the permanent magnet 8 or electromagnet 9, and is held in the holding unit 3.

Next, the control operation of the rotating unit 4 of the holding device 1 configured as described above will be described below with reference to FIG. 3. First, when the ignition switch is turned on, the in-vehicle ECU 6 starts processing and takes in shift information (S1). If the shift information indicates that the position of the shift lever is R, i.e., that the vehicle is in reverse (Y in S2), the in-vehicle ECU 6 controls the rotating unit 4 so that the smartphone 2 is placed horizontally as shown in FIG. 4 (S3). When the smartphone 2 is placed horizontally, the longitudinal direction of the display screen 21 is aligned with the left-right direction. In S3, the in-vehicle ECU 6 communicates with the smartphone 2 to obtain posture information, and if the posture information indicates that the smartphone is placed horizontally, the rotating unit 4 is not rotated, and if the posture information indicates that the smartphone is placed vertically, the rotating unit 4 is rotated to place the smartphone horizontally.

When the shift lever is in the R position, the smartphone 2 communicates with the in-vehicle network to receive video from a camera mounted at the rear of the vehicle and displays the video on the display screen 21, thereby being used as a rear monitor. As shown in FIG. 4, it is easier to use the smartphone 2 as a rear monitor when the smartphone 2 is placed horizontally.

On the other hand, if the position of the shift lever indicates a position other than R, i.e., the vehicle is not in reverse (N in S2), the in-vehicle ECU 6 controls the rotation unit 4 so that the smartphone 2 is placed vertically as shown in FIG. 5 (S4). When the smartphone 2 is placed vertically, the longitudinal direction of the display screen 21 is aligned with the up-down direction. This allows the smartphone 2 to be placed vertically as in normal use when not using the smartphone 2 as a rear monitor. In S4, the in-vehicle ECU 6 communicates with the smartphone 2 to obtain attitude information, and if the attitude information indicates vertical, the rotation unit 4 is not rotated, and if the attitude information indicates horizontal, the rotation unit 4 is rotated to place the smartphone 2 vertically.

Next, if the ignition switch is not off (N in S5), the in-vehicle ECU 6 returns to S2. On the other hand, if the ignition switch is off (Y in S5), the in-vehicle ECU 6 determines whether the removal angle (predetermined rotation position) of the smartphone 2 has been set by the user (S6).

To explain in more detail, the user can use an app for the holding device 1 to communicate with the in-vehicle ECU 6 and set the removal angle to an angle at which the user can easily remove the smartphone 2. The removal angle is, for example, the angle between the up-down direction and the longitudinal direction of the display screen 21. If the removal angle has been set by the user (Y in S6), the in-vehicle ECU 6 rotates the rotating unit 4 to the removal angle set by the user (S7) and then ends the process.

If the set angle has not been preset (N in S6), the in-vehicle ECU 6 rotates the rotating part 4 to the vertical position (removal angle = 90°) as shown in Figure 5 (S8), and then ends the process.

Next, the control operation of the electromagnet 9 of the holding device 1 configured as described above will be described below. The on-board ECU 6 functions as an electromagnet control unit and controls the electromagnet 9. The on-board ECU 6 takes in shift information and speed information in response to the ignition switch being turned on. If the shift information and speed information indicate that the vehicle is traveling, the on-board ECU 6 controls the electromagnet 9 to increase the adhesive force of the smartphone 2 to the holding part 3, and if the information indicates that the vehicle is stopped, the on-board ECU 6 controls the electromagnet 9 to decrease the adhesive force of the smartphone 2 to the holding part 3.

This allows the smartphone 2 to be firmly attached and held in the holding section 3 while the vehicle is moving. In addition, the adhesive force of the smartphone 2 to the holding section 3 weakens when the vehicle is stopped, making it easier to remove the smartphone 2.

Specifically, while the vehicle is moving and while the vehicle is stopped, the in-vehicle ECU 6 passes a current through the coil of the electromagnet 9 so that the magnetization direction of the electromagnet 9 is the same as that of the permanent magnet 8, and the amount of current through the coil while the vehicle is stopped is less than the amount of current through the coil while the vehicle is moving. This makes it possible to make the adhesive force of the smartphone 2 weaker while the vehicle is stopped than the adhesive force of the smartphone 2 while the vehicle is moving.

The on-board ECU 6 may also pass a current through the coil of the electromagnet 9 so that the magnetization direction of the electromagnet 9 is the same as that of the permanent magnet 8 while the vehicle is moving, and reverse the direction of the current flowing through the coil while the vehicle is stopped so that the magnetization direction of the electromagnet 9 is opposite to that of the permanent magnet 8. In this case, the electromagnet 9 generates a magnetic force that repels the smartphone 2, further weakening the adhesive force of the smartphone 2 while the vehicle is stopped.

The in-vehicle ECU 6 also receives model and model number information through communication with the smartphone 2. Since the weight of the smartphone 2 is known from the model and model number information, the in-vehicle ECU 6 may control the electromagnet 9 so that the adhesive force of the smartphone 2 increases as the weight increases.

According to the first embodiment described above, the in-vehicle ECU 6 controls the rotation of the rotating part 4 in response to vehicle information indicating the state of the vehicle, so that the smartphone 2 can be rotated in response to the state of the vehicle without the user's operation.

According to the first embodiment described above, when the vehicle is moving backwards, the smartphone 2 is placed horizontally (the longitudinal direction of the display screen 21 is arranged along the left-right direction), making it easy to use as a rear monitor. When the vehicle is not moving backwards, the smartphone 2 is placed vertically (the longitudinal direction of the display screen 21 is arranged along the up-down direction), allowing the smartphone 2 to be arranged in the same way as during normal use.

According to the first embodiment described above, the in-vehicle ECU 6 controls the magnetic force of the electromagnet 9 so that the force of attraction of the smartphone 2 by the holding unit 3 is weakened while the vehicle is stopped, and controls the magnetic force of the electromagnet 9 so that the force of attraction of the smartphone 2 by the holding unit 3 is increased while the vehicle is moving. This increases the force of attraction of the smartphone 2 by the holding unit 3 while the vehicle is moving, and prevents the smartphone 2 from falling off the holding device 1. When the vehicle is stopped, the force of attraction of the smartphone 2 by the holding unit 3 is weakened, and the smartphone 2 can be easily removed from the holding device 1.

Second Embodiment
Next, a holding device 1B according to a second embodiment will be described below with reference to Fig. 6. In Fig. 6, parts equivalent to those of the holding device 1 shown in Fig. 1 and the like already described in the first embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in the figure, the holding device 1B includes a holding section 3B that holds a smartphone 2, a rotating section 4B, a holding section 5, and an on-board ECU 6. In the second embodiment, the holding section 3B includes a permanent magnet 8 and an electromagnet 9B. The positioning member 7 and the permanent magnet 8 are similar to those in the first embodiment, and therefore a detailed description thereof will be omitted here.

The electromagnet 9B is ring-shaped, with the permanent magnet 8 fitted and fixed in the center. The electromagnet 9B is wound with a coil (not shown) so that the magnetization direction is an axial direction along the front-rear direction, and the north poles and south poles are arranged alternately along the axial direction. In this embodiment, the electromagnet 9B is provided with two north poles and two south poles. The rotating unit 4B includes a rotating shaft 12 and an electromagnet 13 as a second electromagnet. The rotating shaft 12 is fixed to the permanent magnet 8 and is held by the holding unit 5 so that it can rotate freely around the axis along the front-rear direction.

Electromagnet 13 is held by holding portion 5 and is positioned facing electromagnet 9B in the fore-and-aft direction. Electromagnet 13 has a coil (not shown) wound around an axis along the fore-and-aft direction, and has a north pole and a south pole lined up along the fore-and-aft direction. On-board ECU 6 controls electromagnet 13 so that the magnetization direction alternates between the rear side being the north pole, the front side being the south pole, the rear side being the south pole, and the front side being the north pole.

As a result, for example, when the smartphone 2 is in a vertical position, the south pole of electromagnet 9B and electromagnet 13 face each other. At this time, if the rear side of electromagnet 13 is controlled to be the north pole, the rotation stops and the smartphone 2 can be held in a vertical position. Also, if the rear side of electromagnet 13 is switched to the south pole, electromagnet 9B and electromagnet 13 repel each other, generating a rotational force, rotating shaft 12, and rotating smartphone 2 to a horizontal position. When smartphone 2 rotates to a horizontal position, the north pole of electromagnet 9B and the south pole of electromagnet 13 face each other in the front-to-back direction, stopping the rotation and holding smartphone 2 in a horizontal position.

As in the first embodiment, the on-board ECU 6 controls the electromagnet 9B so that the adhesive force of the smartphone 2 to the holding portion 3B is strong while the vehicle is moving, and controls the electromagnet 9B so that the adhesive force of the smartphone 2 to the holding portion 3B is weak while the vehicle is stopped. This allows the electromagnet 9B for holding the smartphone 2 to be used to rotate the holding portion 3B.

Third Embodiment
Next, a holding device 1C according to a third embodiment will be described below with reference to Figures 7 and 8. In Figures 7 and 8, parts equivalent to those of the holding device 1 shown in Figure 1 and the like that have already been described in the first embodiment above are designated by the same reference numerals, and detailed description thereof will be omitted.

As shown in the figure, the holding device 1C includes a holding section 3C that holds the smartphone 2, a rotating section 4C, a holding section 5C, and an on-board ECU 6. In the third embodiment, the holding section 3C includes a positioning member 7C, a permanent magnet 8C, and an electromagnet 9C.

The positioning member 7C has a flat plate portion 71C, a pair of restricting plates 72C, 72C, a restricting plate 73C, a pair of locking arms 74C, 74C, and a positioning protrusion 75C. The flat plate portion 71C is formed in a rectangular shape, and a hole 76C is provided in the center into which the rear end of an electromagnet 9C described later is fitted. The pair of restricting plates 72C, 72C are provided standing forward from both ends of the flat plate portion 71C in the short direction, and restrict the movement of the smartphone 2 in the short direction. The restricting plate 73C is provided standing forward from one end of the flat plate portion 71C in the long direction, and restricts the movement of the smartphone 2 in the long direction.

The pair of locking arms 74C, 74C stand upright from the flat plate portion 71C toward the front, and have locking claws at their tips that lock with the electromagnet 9C in the front-rear direction. The pair of locking arms 74C, 74C are arranged side by side along the longitudinal direction of the flat plate portion 71C. The positioning protrusion 75C protrudes toward the front from the flat plate portion 71C.

The permanent magnet 8C is disk-shaped and, unlike the first embodiment, does not have a positioning hole. The electromagnet 9C is ring-shaped, as in the first embodiment, with the permanent magnet 8C fixed to its center. A positioning groove 91C is provided on the side of the electromagnet 9C along the front-rear direction into which the positioning protrusion 75C is fitted. By fitting the positioning protrusion 75C of the positioning member 7C into the positioning groove 91C of the electromagnet 9C, when the electromagnet 9C rotates, the positioning member 7C also rotates.

The rotating unit 4C has a rotating shaft 14, a gear 15, a gear 16, a rotating shaft 17, and a motor (not shown). The rotating shaft 14 is held by the holding unit 5C so as to be rotatable about an axis along the front-rear direction, and its rear end is fixed to the permanent magnet 8C. The gear 15 is attached to the rotating shaft 14. The gear 16 is attached to the rotating shaft 17 so as to mesh with the gear 15. The rotating shaft 17 is rotated by the motor about an axis along the front-rear direction. When the rotating shaft 17 is rotated by the motor, the rotational force is transmitted to the rotating shaft 17 via the gears 15 and 16, and the permanent magnet 8C can be rotated.

According to the third embodiment described above, there is no need to fix the positioning member 7C to the smartphone 2, making it easy to use.

The present invention is not limited to the above-described embodiment, and can be modified, improved, etc. as appropriate. In addition, the material, shape, size, number, location, etc. of each component in the above-described embodiment are arbitrary as long as they can achieve the present invention, and are not limited.

In the above-described embodiment, a smartphone 2 has been given as an example of an electronic device, but the present invention is not limited to this. The electronic device may be any device having a display screen, such as a tablet.

In the above-described embodiment, the holders 3, 3B, and 3C attract and hold the smartphone 2 by the magnetic force of the permanent magnets 8 and 8C, but this is not limited to the above. The holders may have any structure that can hold the smartphone 2, and may, for example, hold the smartphone 2 by pinching both sides of the smartphone 2 in the short direction.

The rotation control of the smartphone 2 is not limited to the above-described embodiment. For example, when using a navigation app on the smartphone 2, the in-vehicle ECU 6 may control the rotation of the rotating unit 4 so that the smartphone 2 is oriented vertically when going straight and horizontally when turning right or left. Specifically, the in-vehicle ECU 6 communicates with the smartphone 2 to obtain navigation information, and when the navigation information indicates a straight-ahead direction, controls the rotating unit 4 so that the smartphone 2 is oriented vertically.

In addition, in response to a right/left turn instruction in the navigation information or the operation of the turn switch, the in-vehicle ECU 6 determines that it is time to turn right or left and controls the rotation unit 4 so that the smartphone 2 is placed horizontally. At this time, the rotation angle and rotation speed of the smartphone 2 may be controlled in conjunction with information from a steering angle sensor. By placing the smartphone horizontally when turning right or left, map information of the destination after the turn can be confirmed, providing the user with more information.

When the right or left turn is completed, the in-vehicle ECU 6 returns the smartphone 2 to the vertical position. Completion of the right or left turn can be performed based on vehicle position information and information from the steering angle sensor. When returning the smartphone 2 from the horizontal position to the vertical position, the in-vehicle ECU 6 may also control the rotation angle and rotation speed of the smartphone 2 in conjunction with information from the steering angle sensor.

The smartphone 2 may be rotated according to the vehicle state, such as the vehicle's position information and speed, and the type of application. The screen orientation that is easiest to view varies depending on the application. When it is determined that the smartphone 2 is traveling in conjunction with the speed information and a navigation application is being used, the in-vehicle ECU 6 places the smartphone 2 vertically. When a video playback application is being used on the smartphone 2 while the vehicle is stopped, the in-vehicle ECU 6 places the smartphone 2 horizontally. When a video playback application is being used on the smartphone 2 while the vehicle is traveling, the in-vehicle ECU 6 may place the smartphone 2 vertically to make it difficult for the user to watch videos.

In addition, when a navigation app on the smartphone 2 is being used during delivery work, the in-vehicle ECU 6 places the smartphone 2 vertically. Then, when it is determined that the delivery destination is approaching, the smartphone 2 switches to a delivery management app. At this time, the in-vehicle ECU 6 places the smartphone 2 horizontally. When it is determined from speed information and vehicle ignition information that the vehicle has stopped to deliver a package to the delivery destination, the in-vehicle ECU 6 places the smartphone 2 vertically so that it is easier to remove. There are multiple ways to switch applications, such as by touch operation on the smartphone 2 or by switching between voice operations.

In addition, the smartphone 2 may be placed vertically or horizontally depending on the type of application being used. For example, when a navigation application, a map application, an SNS application, or a telephone application is being used, the smartphone 2 is placed vertically. In addition, when a video playback application, an image/video shooting application, a data management application (delivery management), a game, or the like is being used, the smartphone 2 is placed horizontally.
